l v `pplieatieu filed August 29,1895. Serial No. 560,831. (No modeLlTou/ZZ when@ it 71mg/.calmer/1.:- ,Be 1t known that l, YALTER SCOTT, acitiyzen of the United States, and a resident of 'Plainield,V in thecounty of Union and State of'New ersey,A have invented certain new landuseful improvements in Folding Meeh- .anismpf which the following is aspeciication.

VThis invention relates to mechanism' for folding sheets, and hasreference to such'a construction of the same that cuts or sheets@delivered thereto may be folded without beingcollected, or byla simpleadjustment of "the mechanism may be collected and folded. Lit isimmaterial whence or how the sheets are supplied to, the foldingmechanism.

The invention includes a carrier provided 'with a number of spacesthrough which foldingbla-des may be protruded, folding-blades differingin number from said spaces, said blades and carrier having differenttimes of eifevolution, so a blade passes the place where thefold isgiven witheach space, th ns allow ing of folding the-sheets or cutswithout any collecting. lf one or more of the blades be renderedinoperative, collecting of sheets take: place`, followed by folding- Theinvention also includes a rotating carrier-cylinder combined with afolding-blade (or blades) havin g an' axis of revolution eccentric 'tothe axis of the cylinder. The times of revolution may be asin the firstcase men- .The invention also includes other features,

as willbe hereinafter more fully pointed out.

The particular embodiment of the invention shown in the accompanyingdrawings and hereinafter described includes a carrying -or collectingcylinder Iprovided with three spa-ces through which folding-blades maybe protruded and two folding-blades revolving in times different fromthe times of rotation of the cylinder and having at least two motions,onc of revolutionand the other of rotation. Preferably the motion ofrevolution of .theblades is about an*l axis eccentric to that of thesaid cylinder, asthis avoids any in-andled/ting of two non-successivecuts orsheets out or radial motion of the blades in addition tothe twomotions ab'ovenamed. make three revolutions about their axis eccentricto that of the'cylinder to two revolu' tions of the cylinder,th usallowing of. the colv being. omitted. .carrier and folding devices ormechanism,

The blades before folding,- one blade being inoperative, or the foldingof the cuts orsheets separately, both blades being in operation. Thisconstruction permits of collecting but two cuts before thefolding. if amechanism capaci= tated to collect three or more cuts or none bedesired, the rule is to have a carrier provided with a number of spacesthrough which folding-blades may be protruded greater vby one.

and a numberof blades equal .to the number of cuts'to' be collected. Therevolutions of the cylinder and the blades are to each other as thenumber of blades is to the number of saidspaces. l

The invention is shown two rotary web-perfecting printing-presses U'andL, Aof usual or suitable construction, and au longitudinal folder F, towhich the webs w w' are led around rollers -r and turn ers in awell-known manner. From the rollers. e f of the fold erF the webs passbetween the cutting-cylinders m 01, Where they Iare severed into cuts orsheets. .l From this point the-.cuts pass to Athe mechanism embodyingthe present invention. y

Aj rotatable v carrier-cylinderl C, formed of Figs. 8 to 17, bothinclusive, are diagrams in connection with IDO i makesone (l) turn totwo-thirds of a turn fof cylinder C, andtha't the cams 1-5 16 are' ends2 Il, Figs. Sand 4, hoops 4, and. longitu- The spaces a b o betweentheties 5 permit of the protrusion of' suitable folding-blades. Thiscylinder is to be provided with suitable sheet-retainers, as pins orgrippers, the latter being shown at 7 as c'o'- acting with the ties 5tohold` the leading or front edges of the cut-s.

The lcylinder C is 'driven by means ofthe toothed gears 8 on or formingthe ends 2 3, the gears d'9? on the shaft 10,' which is journaled in theframework A, the gear 1l on a similarly-journaled shaft 12, and the gear13 on the side shaft 14". 'The'grippers 7 a'rej opened at the propertimes by suitable means, as the movable cams 15 16, which are pivoted tothe framework, las atv17 18. 'These cams- 15 1G are suitably operatedfrom a convenient lpart ofthe machinery, as by the rods 19 20,

straps 21 2i?, and eccentrics 23 24 on shaft 12. The gears 9n 11 are inthe proportion of on-e to two, and gears 9 S are in the proportion ofone to three, whence it follows vthat shaft l2 t each alternately'in andout of the positions in Whichthey open the grippers 7. This' is theiroperation when sheets are collected on cylinder C, `it being understoodthat any'set of grippers aft-er'bcing opened to take a first sheet bythe cam is not opened by cam 16 until suchset passes that earn thesecond time.' For this reason the eccentrics 2324 are placed at oppositesides of shaft 12. A

The sheets folded by the blades .a and the'- rollers 30 v31 are conveyedaway by the sets of tapes 2S 32 (the former set running on rollers orpulleys Zland` roller SOand the latter set running on rollers or pulleys33 and roller. 1 31) and the guide ba'rsor fingers 41 tothe re'v ceiverR.
